PLow.

Specification of Letters Patent.

Patented July 16, 1907.

To all whom it may concern:

`Be it known that I, CHARLES W. MCWANE, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented a new and useful Plow, of which the follow- .ing is a specification.

yThis Ainvention relates more particularly to that class of plows ordinarily designated double-mold board or middle breaker plows, though there are features herein disclosed and claimed that are not necessarily limited thereto, but are capable of advantageous use in plows of other types.

One of the principal objects is to provide a novel,

ycomparatively simple and compact combination of parts, which can be readily assembled and dismem- 'bered and forms a strong, rigid and effective struea front elevation thereof. Fig. 3 is a rear elevation of said plow. Fig. 4 is a vertical longitudinal sectional view through the body of the plow. Fig. 5 is a cross sectional view on the line 5 5 of Fig. 4. Fig. 6 is a detail perspective view of the standard. Fig. 7 is a 'similar view of the shoe. Fig. 8 is a bottom plan view of the point or share, Fig. 9 is a detail perspective view of the abutment block.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a standard is employed, which is substantially U-shaped in cross section, and comprises sidewalls 10 connected at their lower ends by a cross web 11. The side walls have curved front edges and substantially vertical rear edges, and consequently said side walls taper towards their upper ends. The standard may be of pressed steel, malleable iron, or any other Imaterial found suitable for the purpose.

An abutment block 12 is located between the upper ends of the side walls 10, and secured in place by any suitable means, as for instance, bolts 13. This abut- `ment block has a recess 14 in its front face, from which projects a clamping bolt 15, having an offset end 16, located in a socket in the block, the other end of said bolt extending vertically and having a nut 17, threaded thereon. A beam 18, of any suitable structure, has a downwardly extending rear end portion 19 fitted between the side walls and bolted thereto, as shown at 2.0. This beam abuts against the rear side of the block 12. Handles 2l are secured at their lower ends to the side walls l0 by the lower bolt 20 that fastens the beam in place, and braces 22, secured to the upper end ofthe standard by the upper bolt 20, are connected to the handles 21, 'as shown at 23. Still other braces 24 preferably connect the beam 18 and the handles.

The side walls 10 are provided along their curved front edges with outstanding integral wings 25, and secured thereon by suitable bolts 26 are mold-boards 27. The mold-boards terminate short of the lower ends of the wings, and have their inner edges spaced apart. A shim 28 is arranged between the inner edges of the mold-boards, and has its upper end extending over the front face of the abutment block 12, covering the recess 14, and engaging the clamping nut 17, as clearly shown in Fig. 4. The lower' end of the shim 28 is preferably thickened, as shown at 29. A point 30 rests against the lower ends of the wings 25, and abuts against the lower ends of the mold-boards and shim, being Secured in place by bolts 31 passing through the lower ends of-the wings. This point furthermore has a rearwardly extending rib 32 that engages beneath the lower end or thickened portion 29 of the shim 2S.

A nose member, in the form of a bar 33, is slidably mounted on the web 11 of the standard between the side walls 10 thereof, and the underside oi the point is recessed, as shown at 34 to permit the passage of the nose piece beneath the same. The ends of the nose piece or bar are sharpened, as shown at 35, and its upper face is preferably provided with a series of notches 36. A tooth 37, formed upon the underside of the point or share is arranged to engage in one of the notches 3G, and thus when the point is fastened in position, it will be interlocked with the nose member, and securely hold it against movement.

A shoe 38, for protecting the lower end of the standard against wear and properly positioning the plow body with respect to its work, is secured to said standard. This shoe consists of a bottom or runner wall 39, having upwardly curved ends 40, with spaced side walls 41 and 42, the former being integral with the bottom wall, the latter being removable. These side walls have upstanding ears 43 that embrace the lower portion of the standard and are secured thereto by bolts 44. The front upturned end of the bottom wall 3S is of less height than the rear upturned end, and terminates short of the upper edges of the side walls. being abutted against the underside of the standard, as illustrated in Fig. 4. A transverse rib 45, formed in an intermediate portion of the shoe, is arranged to abut against the underside of the standard at its rear end,

- so that the bottom of the shoe will be disposed at an inclination with respect to the bottom of the standard.

It will be evident that this is an exceedingly simple structure, and that all the parts are fastened to the novel form of standard, said parts being so arranged, however, that they reinorce and brace each other. The structure is such that the parts can be readily fitted and assembled, and the elements, which are subject to the greatest amount of wear, are entirely accessible, so that they may be removed at any time, and replaced byv others without entirely dismembering the plow. Thus, either mold-board may be removed at will, and the shim can be freely detached either by loosening the nut 17, or the point 30. Moreover, when the latter is loosened, and detached, the nose bar can be adjusted or reversed but said'nose bar is'efliciently held when the point is secured in position.

From the foregoing, it is thought that the construction, operation, and many advantages oi the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.
